c1_LIR.hpp defines a row of functions guarded by platform
defines. This is bad style and hinders new platform ports.
(I'm working on S390 aka Z :))
This change removes the majority of these defines. It introduces
common headers, and moves implementations to c1_LIR_<cpu>.cpp files.
It guards single_softfp() and double_softfp() by __SOFTFP__.
This is not used in any openJdk platform. I can not test this
on the closed platforms ARM32 and PPC32.
It removes the guard around the LIR_Address constructor. There
is no point in guarding this code, verify() assures by
assertions that it can not be misused. I also introduce a new
constructor that leaves out the scale argument and introduced
some usages on X86.
This change also moves verify() to the new platform files. In the
header, LIR_ADDRESS_PD_VERIFY was used to guard usage
of pd_verify(). Neither of these are used in openJdk. If this define
is used in the closed ports pd_verify() must be renamed to verify().
The code that was previously guarded by ARM, ARM32 or PPC32 is
moved to a properly guarded section in c1_LIR.cpp. Actually,
it should be moved to according new files c1_LIR_<cpu>.cpp in
the closed ports. But this way the change should basically
work for the closed ports.
I added fnoreg on x86 to note down the code similarly on all
I cleaned up a flag with a limited range on PPC_32.
Please review this change. I please need a sponsor.
I built and tested this on linuxx86_64, solaris_sparc and the ppc platforms.
